DRIVING WHEEL BOX FOR LOCOMOTIVES AND THE LIKE.

Application filed March 2a, 1923. Serial No. 628,171.

To all whom it may concern:

Be it known that I, JOHN F. BYRNE, a citizen of the United States, residin at Lincoln, in the county of Lancaster and tate t3 of Nebraska, have invented certain new and useful Improvements in Driving-VVheel Boxes for Locomotives and the like, of which the following is a specification.

' This invention relates to driving-wheel boxes for locomotives or the like.

One of the primary objects of the invention is to provide a quick and eflicient means for removing the driving-wheel box for replacement or repairs.

A further object of the invention is to provide an eflicient means for adjusting the lateral motion of a locomotive due to wear of certain of the parts.

A still further object of the invention is to provide a driving-wheel box of the character described which shall be simple in construction, relatively inexpensive in manufacture and which can easily be applied to any locomotive or the like now in use.

Other objects will appear from the description hereinafter. The drawings are intended merely to indicate one embodiment of the invention and in the manufacture of the invention certain mechanical changes may be made without departing from the scope of the invention which, therefore, is not intended to be restricted to the embodiment illustrated.

With the various objects in view the invention consists in the novel construction, arrangement and combination of parts as hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. co In the drawings, which illustrate one embodiment of the invention, Figure 1 is an elevation of the driving- Wheel box of a locomotive embodying my invention, the driving-wheel being removed. Figure 2 is a section on line 22 of Fig. 1 looking in the direction of .the arrows.

Figure 3 is a section on line 33 of Fig. 1 looking in the direction ofthe arrows. Figure 4 is a section on line 44: of Fig. 3 'looking in the direction of the arrows.

Figure 5 is an elevation showing the opening in the locomotive frame which receives the driving box.

Figure 6 is a perspective view of the adjusting wedge.

Figure 7 is a perspective view of the shoe.

Figure 8 is a perspective view of the re movable flange.

Figure 9 is a perspective view of the wedge-shaped removable flange. 1 Figure 10 is a section on line 1010 of Figure 11 is a perspective view of one of the split bearing ring members.

Figure 12is a perspective view of the ringshaped bearing.

Figure 13 is a detail'showing the means to raise and lower the adjusting wedge.

In the drawings 1 represents a locomotive frame, 2 the frame jaws, and 3 an axle journal upon which latter the usual drive-Wheel 4 is fixedly secured. The frame 1 is provided with an opening 6 within which the driving-wheel box 5 is fitted.

7 indicates the usual bearing made of anysuitable material, and 8 is the usual collar which is cored out as shown in Fig. 3 to provide a receptacle for oil or grease.

The shoe 9 forms a bearing surface for the front side of the box and the wedge 10 provides means for adjustment. In practice the wedge 10 is set up tight enough to prevent any play between the box and the shoe 9 but not so tight as to prevent the box from moving vertically between the frame jaws 2.

The box 5 is provided with flanges 11 upon the inner side of'the jaws 2 and with removable flanges 12, 13, on the outer side of said aws.

The opening 6 in the frame is inclined at one side as at 6 against which inclined face the inclined face 10 of the wedge 10 is adapted to bear. The box 5 has an inclined bearing face 5 inclined similarly to the face 6 and against said face 5 the inclined face 13, of the flange 13 is seated. The flange 12 has a non-inclined bearing face 12' against which seats the 11on-inclined bearing face 7' of the box. The flange 13 is removably secured in position by means of bolts 16 which pass through holes 17 in the flange and screw within openings in the box, while the flange 12 is removably secured to the box by means of bolts 16 passing through holes 17 in flange 12 and screwing within openings in the box.

The flanges of the box slide on the filler strips 14 and 15 which are permanently secured by welding or otherwise to the jaws 2 of the locomotive frame.

It will be noted in Fig. 2 that the flanges 11, 12 and 13 maintain the box 5 in position between the jaws of the locomotive frame.

At a given distance away from the box 5 a thrust collar 18 is secured upon the journal and between said collar and the box a split collar 19 made in two halves is fastened by bolts 20 to the journal 3. One end of the collar is enlarged as at 21 and is provided witha depression 22 to house the split ring bearing 23 which may be of any suitable bearin metal. The bearing 23 is made to fit tight y within the depression 22 and abutting said bearing is a substantially U- shaped bearing 24 which fits tightly within depressions 25 of the flanges 11.

As the journal 3 revolves, the split collar 19 secured thereon will revolve with it, and as the split ring bearin 23 fits tightly within the split ring, said bearing will revolve with the journal. It will be noted that the bearing 24 does not revolve.

It will thus be seen that as the split ring bearing 23 is fixed to the journal and the U-shaped bearing 24 is fixed to the locomotive frame, the latter will be permitted to have the usual lateral motion, which is desirable, and to regulate the extent of such motion 1 provide a distance piece 25 arranged between the split ring 19 and the collar 18. A thicker or thinner distance piece may be used to vary the amount of lateral play. As the bearings 23 and 24 wear, a thicker or an additional piece 25 may be inserted. The distance piece is made in two halves and spot welded.

The contacting surfaces of the bearings 23 and 24 will have a revolving frictional motion and a hammering motion, revolving when the. locomotive is running straight ahead and hammering when it is rounding a curve.

At the bottom of the adjusting wedge 10 is a T-shaped opening 26 within which fits a nut 27. An adjusting bolt 28 screws within the nut until the end of said bolt reaches the upper part of the slot and bears against the surface 28 ofthe wedge. This will make the adjusting bolt 28 immovable with respect to the wedge. The bolt 28 passes loosely through an opening provided in a yoke 29 bolted to the frame. Nuts 30 screwing upon the bolt 28 on opposite sides of the yoke serve to fixedly se"ure the bolt in its adjusted position. It will thus be seen that the wedge 10 can be raised 'by .turnin the outer nut 30 reversely upon the bolt an then turning the latter to the right until the wedge is raised sufficiently and then adjusting the nuts 30 against the yoke.

When it may be desired to lower the wedge the inner nut 30 is raised upon the bolt and the latter turned reversely to permit the wedge to lower by gravity, after which both nuts are again tightened against the yoke.

To remove the box 5 for replacement or repairs all that is necessary is to detach the split ring 19, remove the flanges 12 and 13, disengage the bolt 28 and unfasten the collar bolts 31. The box 5 is then ready to be slipped towards the collar 19 and then raised from the journal.

It will be seen that I have provided a driving-wheel box which is simple in construction, relatively inexpensive in manufacture, efficient in operation and which can be uickl removed and replaced.

l%hat claim and desire to secure by Letters Patent is 1. The combination with the frame of a locomotive or the like, of a driving-wheel box carried by said frame, flanges upon the inner side of the box, flanges upon the outer side of the box and removably secured thereto, and filler strips arranged intermediate the various flanges and the frame.
